Design And Realization Of Internet Exam System For Training Of Enterprise

With the development of modern distance education, it will make great influence on modern distance education to develop and apply of internet exam system including modern exam theories, methods and modern information technology.Based on the state-of-art of modern distance education, according to the background of IES and theories of modern soft engineering, the IES was established through a series of research works, such as requirement analysis, modeling, model design, program and testing. The IES could meet the requirements of inner exams of a modern information technologic enterprise. The data-base of test questions and forming of test papers were investigated thoroughly. The method to estimate difficulties of test papers with expectation test score (ETS) was given firstly. And it was realized to control the difficulty of the test papers easily by persons. The schemes of test papers forming were designed and realized in details. The data base was unstandardized and storaged for the aim of reducing the inquiring time, and the IES has a large capacity of loading. The technology of information exchange asynhronously, AJAX, was used during the development of GUI for being used easily and looking clearly. The reponse time of IES is very short. At the end of the present thesis, the summary and the expectation of of the present thesis were made out.The method to estimate difficulties of test papers with expectation test score (ETS) was used during the process of developing of the IES. The test and judgment of subjective test questions could be carried out with IES, and which makes a great advancement over the traditional test system. The IES developed in present thesis could contain 1,000 persons at the same time. The IES developed in present thesis has no problem and has not been intermitted after near half year's working. Model conception was used during the developing of the IES, and the codes of each model could be used repeatly and extended easily. The IES could be references of similarity inter exam system.
